IMPROVEMENT IN GUN-LOCKS.

Specification forming part of Letters Patent No. 138,145, dated April 22, 1873; application filed October 27, 1871.

To all whom it may concern:

Be it known that I, CHARLES GORDON, of Goswell Road, in the county of Middlesex, England, have invented certain Improvements in the Construction of Breech-Loading Fire- Arms, of which the following is a specification:

My invention consists in the arrangement of a sear and sear-spring in combination with certain other mechanism, whereby the discharging apparatus of breech-loading fire-arms is actuated in a simple and eicient manner, and which will be more clearly understood by reference to the annexed drawing, in which- Figure l represents the right-hand side of the lock-plate with the hammer cocked 5 Fig. 2, a similar view with the hammer down; Fig. 3, a view of the left-hand side of the lockplate with the hammer cocked 5 Fig. 4, a similar view with the hammer down; and Fig. 5, a longitudinal section of a gun with my improvement applied.

For the support of the mechanism which forms the subject of this invention, a flat metallic plate, e, is employed, and which is placed in a vertical position in a chamber constructed for that purpose in the stock of the fire-arm, immediately in the rear of the breech-action. rlhe sear, which consists of a steel bar, a, is pivoted to one side of the plate by means of a screw-pin, and on the other side of the plate is placed the main and sear spring b, one end of which is mounted on a screw-pivot fixed in the plate e. Above the sear is placed a bent trigger-bar, f, the forward end of which is' pivoted to the plate e, and the rear end thereof provided with a stud or pin capable of working in an upward or downward direction in a curved slot, g, formed in the rear end of the vertical plate e. The trigger-bar f is pressed downward by the action of the main and sear springs b, which rest on the end of the stud or pin when the mechanism is in its normal state of inaction. At the forward end of that side of the vertical plate e, on which the sear a is situated, a hammer, c, is pivoted, the same being connected by the pivot or pin upon which it turns with jointed levers d, which are placed on the other side of the vertical plate e, and pivoted to the forward end of the sear-springf. On the edge of the hammer c is formed a notch, into which the forward end of the sear a enters and holds it in its normal position, and on the hammer is also formed a projecting piece, provided with a flat face or surface capable of acting as a hammer. This flat piece is pressed down by the breech-piece when the latter is withdrawn, until the sear a takes into the before-mentioned notch on the hammer c, thus cooking the gun by the act of withdrawing the breech-bolt, as will be clearly understood by reference to Sheet 2 of the annexed drawing. Upon the trigger-bar f being raised, the stud or pin which is attached thereto, traverses the curved slot g, thus pressing the rear portion of the main and sear spring b upward, and soactuating the jointed levers d at the forward end thereof, and releasing the hammer c from the sear a.. The former is thereupon rotated on its Witnesses:
